The Ecotricity Greenbird is back for the big ice challenge!

After breaking the world land speed record in March the Greenbird team are back for more, this time on the frozen lakes of Montana. Not content being the worlds fastest naturally powered vehicle on land, the British team are chasing the accolade for an ice craft too!

The highest accurately (GPS) recorded speed for a wind-powered ice craft is 84 mph and the team are confident about their chances for a second world record.
